The npm package @or-sdk/chat has been identified as containing malware. According to the GitHub Advisory (GHSA-mxcc-ccp6-gxp4), any system with this package installed or running should be treated as fully compromised.

The advisory warns that all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system. While the package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the package installation, as the attacker may have gained full control of the system.

This is a critical supply chain incident affecting the npm ecosystem.
